Mechanical properties of unidirectional, porous polymer/ceramic composites for biomedical applications

نویسندگان

چکیده

The addition of a ductile phase to porous ceramic can help overcome the brittleness ceramics. Yet, most studies so far have focused on processing and characterization dense composites. Alternatively, unidirectional pores improve strength Here we combine two approaches show simple strategy obtain highly porous, ceramic/polymer We infiltrated ice-templated zirconia scaffolds with polymer or solution. After centrifugation evaporation solvent, composites porosity greater than 60% were obtained. Our results demonstrate that (PCL) increase both toughness while maintaining high porosity, whereas brittle (epoxy) has seemingly no impact fracture properties. This approach could provide materials are easier handle for biomedical applications.

The mechanical properties of unidirectional all-polypropylene composites

The creation of highly oriented, co-extruded polypropylene (PP) tapes allows the production of recyclable ‘all-polypropylene’ composites, with a large temperature processing window (O30 8C) and a high volume fraction of highly oriented PP (O90%). These composites show little deviation of mechanical properties with compaction temperature. This paper introduces all-polypropylene composites and re...

Mechanical properties and failure behavior of unidirectional porous ceramics.

We show that the honeycomb out-of-plane model derived by Gibson and Ashby can be applied to describe the compressive behavior of unidirectional porous materials. Ice-templating allowed us to process samples with accurate control over pore volume, size, and morphology. These samples allowed us to evaluate the effect of this microstructural variations on the compressive strength in a porosity ran...

Nanocrystalline forsterite for biomedical applications: synthesis, microstructure and mechanical properties.

Forsterite (Mg2SiO4) because of its exceptionally high fracture toughness which is close to that of cortical bones has been nominated as a possible successor to calcium phosphate bioceramics. Recent in vitro studies also suggest that forsterite possesses good bioactivity and promotes osteoblast proliferation as well as adhesion. However studies on preparation and sinterability of nanocrystallin...
